Invarianza, tempo e improvvisazione musicale.
Get PDFThe notion of invariance permeates different research areas and often takes on different meanings. In different fields (psychology, phenomenology, physics, and ethics) the invariance concept attempts to explain the mechanisms of perceptual grouping. In this article invariance is considered a structural condition of our way of perceiving music and especially musical improvisation. It helps to understand the relationship between musical improvisation and nonlinearity, i.e. between what is transformed and what remains unchanged in the process of improvisation. I argue that every musical improvisation whose characteristics are nonlinear implies perceptual invariance with respect to time
Improvvisare la verità. Musica jazz e discorso filosofico
Get PDFImprovisation is specific of some arts, like jazz music, but, as a practice, it is part of almost all complex human practices, included the professional ones, because of the role it plays in transforming and developing them. Improvisation plays an important role even in philosophical discourse, whose process is comparable with the jazz music process. However, in both fields a circularity arises, which creates a problem concerning the validity and the normativity of their whole processes. A reflection on the two fields suggests some possible solution paths.
 
La debole forza messianica dell’improvvisazione. Per un nuovo paradigma dell’agire
Get PDFThe themes of improvisation and of unfulfillment share many traits. Both take a stand against the «absolute norm» imposed by the technocratic consumer society; both re-explore discarded options in search for a brand new solution. Accordingly, action (including political action) must be reconsidered in light of the theme of reversibility, what Italo Calvino and Michelangelo have shown us about the process of artistic creation. Further confirmation of this is offered by Luigi Pareyson’s theory of formativity
La materia di Elena e del suo doppio: le derive artistiche di un mito
Get PDFThe paper reconsiders some aspects of the ancient legend of Helen, paying particular attention to her divine origin continued in the Spartan and Laconian traditions, which were collected and elaborated by the poet Stesichorus in two different versions of his Palinodia. Here he said that Proteus kept Helen in Aegypt giving to Paris / Alexander an eidôlon of Helen in her substitution. The author wonders about the matter of this eidôlon. The ‘drift’ of this myth is then considered in relationship with the history of visual arts, that seems to have been influenced by the fame of Helen’s beauty from Parrasios and Zeuxis’s time until modern age, in strict connections with its literary afterlife. 
Derive e macchinazioni mitologiche. Omaggio a Furio Jesi
Get PDFThe expression “mythological machine” indicates for Furio Jesi a complex autopoietic apparatus which incorporates and transfers collective experiences together with the socialized knowledge of myth, while it reproduces, with political purposes, mythologies, tales, narrations and artistic figurations. “Mythological materials” are products historically-verifiable by the machine, whereas the “myth” is the invention of something to whose autonomous existence the machine alludes. The science of mythology is the study of the internal mechanisms of the mythological machine, the analysis of the inner and autonomous existence linguistic circulation that makes those materials mythological. The science of myth is instead the typical science of what historically does not exist which is therefore translatable in the analysis of the different modalities of the myth
Alla ricerca dell’indeducibile. Esperienza dell’improvviso e limiti della norma nella filosofia di Platone
Get PDFBasing on the characterization of exáiphnes in Parm., 156 c 8-157 b 3, as well as of the relationship between téchne and nómos in Polit. 294 a 6-299 e, an integration of Plato’s philosophy into the contemporary discourse concerning improvisation is attempted. Special attention is given also to the description of Socrates’ midwifery (Theaet., 149 a 1-151 d 3), since by means of Plato’s description Socrates’ activity can be perceived as quintessence of a practice which, like improvisation, without any predetermination, while concretely proceeding invents the norm consonant with each singular situation of ist proceeding
The Exit from the Cave: Digitization of Reality and Freedom
Get PDFThe essay proposes an interpretation of the myth of the cave as a passage from a digital ontology (that of the cave) to a non-digital ontology (outside the cave). This passage implies a reconsideration of Parmenidean and Pythagorean ontology, for which the discovery of incommensurable magnitudes is central. In particular, it allows an exteriority (as difference, negativity, dynamis, and so on) to a given system to be conceptualized, in which the possibility of an exit and then of freedom lies
Pluralité de “spuntos” et formativité audiotactile : un regard sur l’improvisation musicale collective
Get PDFThis paper looks at the interactional-improvisational aesthetic experience based on Luigi Pareyson’s notions of “formativity” and “spunto” as well as on the concepts and the taxonomy of Vincenzo Caporaletti’s audiotactile formativity theory. On the theoretical ground, we propose a deeper investigation of the key concepts in the audio tactil phenomenology, such as the “audiotactile principle” [ATP] and the “audiotactile conceptual schemes”. Original concepts for the study of musical interaction are also developed, noticeably the notion of the “interactional formative space” [IFS]
The Problem of the Ontology of Law between Vocation to the System and Teleological Rationality
Get PDFThis paper aims to address the problem of the ontology of law investigating the foundation of the systematic nature that belongs to it as a legal system bearer of an “order”. For this purpose, taking in a comparative consideration three different models, the positivism, the axiological-constitutional one and the classical-metaphysical one, subjects such as the person, the teleological rationality and the natural law are analyzed and discussed in their foundational value and in their specific function
L’improvvisazione creatrice Ricoeur, Florenskij e Balthasar: tra sistemi di riferimento e libertà creativa
Get PDFThe aim of this paper is to reflect on improvisation by means of discussing the relation between system and freedom. I begin with a reflection on the meanings of improvisation. Than, following Ricoeur’s philosophy and Florenskij’s iconology I show that creativity works like an innovation within the tradition. At the end, I claim that Balthasar’s theological aesthetics gives interesting contributions to the hermeneutic of testimony, that, in turn, helps to understand why the connection between system and freedom is key to the process of improvisation
